Radiotherapy, commonly known as "baking electricity" and "shining light", is a method of treating tumors using ionizing radiation. "Radiotherapy" is a familiar term to tumor patients. It is one of the main treatments for malignant tumors, which uses radiation to kill tumor cells for the purpose of controlling the growth and spread of cancer cells. It has only a few decades of history, but is developing rapidly. From the initial discovery of radium by Madame Curie and the use of radium therapy, to the deep x-ray treatment, and in the 1950s, the use of cobalt 60 treatment machine and later gas pedal treatment. Radiation is invisible to the naked eye and can be produced by the decay of radionuclides, by X-ray machines or by various types of gas pedals. Radiation therapy is widely used in the treatment of tumors, and 60% to 70% of tumor patients have to apply radiation therapy in the course of treatment, which can be divided into radical treatment and palliative treatment according to the purpose of treatment. With the updating of therapeutic equipments and improvement of technology, the efficacy of radiation therapy has been greatly improved, and certain tumors such as head and neck tumors including nasopharyngeal carcinoma, tonsil cancer, laryngeal carcinoma and Hodgkin's disease have better efficacy, and palliative radiation therapy can be carried out for patients with advanced tumors in order to achieve the functions of pain relief, hemostasis and anti-inflammation to alleviate the pain of the patients and improve the quality of their survival.
Interventional therapy is the introduction of special catheters, guide wires and other precision instruments into the human body under the guidance of medical imaging equipment to diagnose and locally treat internal pathologies. Interventional therapy applies digital technology to expand the doctor's field of vision, with the help of catheters and guide wires to extend the doctor's hands, and its incision (puncture point), which is only the size of a grain of rice, without having to cut through the human body's tissues, can treat many diseases that could not be treated in the past, and which must be operated on or have poor efficacy of internal medicine treatments, such as tumors, hemangiomas, and various kinds of bleeding. Interventional therapy is characterized by no incision, little trauma, fast recovery and good results.
Chemotherapy is a kind of treatment using chemical drugs to kill tumor cells, inhibit the growth and reproduction of tumor cells and promote the differentiation of tumor cells. It is a systemic treatment, which has therapeutic effects on primary foci, metastatic foci and subclinical metastatic foci. The disadvantage is the poor selectivity of chemotherapeutic drugs, while achieving therapeutic effect, often appear different degrees of toxic side effects, chemotherapy process of physical debility, mental depression, sweating, white blood cells and platelets, red blood cells, blood pigment decline ensue, and even chest tightness palpitations, liver and kidney function damage, forcing the patient to stop the treatment.
